How to set up and solve a word problem involving the words "total of", altogether, together, "sum of", etc. This is the 6th out of 12 in the solving word problems series. The other three series are "Solving Equations", "Factoring" and "Graphing".
instead of doing all of that i justdivided 204 into 2 parts then subtracted 15 from one of the "120's" then i had 105 then i subtracted 105 from 210 and got 99 so my final answer is 99kg and 105...is that still correct?
Although 99 + 105 = 204, the two are not 15 kg apart. Sometimes, a short cut works, but I prefer to teach a logical approach that yields the correct answer every time no matter how hard the problem is worded.
